Prediction of the 10-year course of borderline personality disorder.

OBJECTIVE: The purpose of this study was to determine the most clinically relevant baseline predictors of time to remission for patients with borderline personality disorder. METHOD: A total of 290 inpatients meeting criteria for both the Revised Diagnostic Interview for Borderlines and DSM-III-R for borderline personality disorder were assessed during their index admission with a series of semistructured interviews and self-report measures. Diagnostic status was reassessed at five contiguous 2-year time periods. Discrete survival analytic methods, which controlled for baseline severity of borderline psychopathology and time, were used to estimate hazard ratios. RESULTS: Eighty-eight percent of the patients with borderline personality disorder studied achieved remission. In terms of time to remission, 39.3% of the 242 patients who experienced a remission of their disorder first remitted by their 2-year follow-up, an additional 22.3% first remitted by their 4-year follow-up, an additional 21.9% by their 6-year follow-up, an additional 12.8% by their 8-year follow-up, and another 3.7% by their 10-year follow-up. Sixteen variables were found to be significant bivariate predictors of earlier time to remission. Seven of these remained significant in multivariate analyses: younger age, absence of childhood sexual abuse, no family history of substance use disorder, good vocational record, absence of an anxious cluster personality disorder, low neuroticism, and high agreeableness. CONCLUSIONS: The results of this study suggest that prediction of time to remission from borderline personality disorder is multifactorial in nature, involving factors that are routinely assessed in clinical practice and factors, particularly aspects of temperament, that are not.

Emotion dysregulation and the development of borderline personality disorder.

We review the role of emotion regulation in borderline personality disorder (BPD). We briefly discuss the historical development of BPD as a disorder where emotional regulation plays a key role. We review the concept of emotion regulation in general and explore both one-factor and two-factor models of emotion regulation. We discuss cognitive and attentional aspects of emotion regulation, and explore these regulatory controls as operating as both voluntary as well as automatic processes. We then turn to other neurophysiological models of emotion regulation in general and examine how those models, both neurophysiologically and neuroanatomically, are expressed in individuals with BPD. We examine how neuroimaging, both anatomical and functional, reveals the roles that various neuroanatomical structures play in the regulation of emotion in BPD. We conclude by creating a neurodevelopmental model that describes how a complex matrix involving the interplay of constitutional/biological predispositions with environmental stressors as well as with parental effectiveness in response to the child's emotion expression can impact key aspects of adult cognitive, affective, interpersonal, and behavioral functioning that culminate in a diagnosis of BPD.

Disinhibition and borderline personality disorder.

We review different conceptions of inhibitory control that may be relevant to the regulatory problems featured in borderline personality disorder (BPD). These conceptions have often been framed with regard to personality traits of inhibitory control, but can also be related to cognitive measures of response suppression as well as affect regulation. Reactive behavioral inhibition is relatively unstudied in relation to BPD. A substantial amount of literature links executive function problems with BPD, but that literature has not isolated executive response inhibition nor been controlled for other personality disorder symptoms of antisociality, attention-deficit/hyperactivity disorder (ADHD), or depression, anxiety, or posttraumatic symptoms. We therefore conducted a study of this question looking at BPD symptoms in an adult sample with a small number of BPD subjects and other disorders. Results indicated that symptoms of BPD were correlated with response inhibition (measured by stop signal reaction time) even after controlling for the overlap of stop inhibition with ADHD, antisociality, and other Axis II disorder symptoms. We conclude by hypothesizing discrete developmental routes to BPD, based on different mechanism breakdowns, which would be amenable to empirical investigation at the cognitive or trait level of analysis.

Adult experiences of abuse reported by borderline patients and Axis II comparison subjects over six years of prospective follow-up.

The main objective of this study was to assess the rates of adult experiences of verbal, emotional, physical, and sexual abuse reported by borderline patients and Axis II comparison subjects during 6 years of prospective follow-up. A semistructured interview was administered to 290 borderline patients and 72 Axis II comparison subjects during their index admission. A follow-up analogue to this interview was administered at three contiguous 2-year follow-up periods. Over 94% of surviving patients were re-interviewed at all three follow-up waves. The rates of all four forms of reported abuse declined significantly over time for all subjects considered together. However, each of these types of abuse was reported by a significantly higher percentage of borderline patients than Axis II comparison subjects. When the presence of these forms of abuse was used to predict time to remission, all but sexual abuse were strongly associated with the failure to achieve symptomatic remission from borderline personality disorder. Taken together, the results of this study suggest that the rates of adult abuse reported by borderline patients decline significantly with time but remain relatively high. They also suggest that adult experiences of abuse are strongly associated with a failure to remit from borderline personality disorder.

Psychosocial functioning of borderline patients and axis II comparison subjects followed prospectively for six years.

The purpose of this study was to determine the course of the psychosocial functioning of patients with borderline personality disorder (BPD) over 6 years of prospective follow-up. The psychosocial functioning of 290 patients meeting both DIB-R and DSM-III-R criteria for BPD and 72 patients meeting DSM-III-R criteria for another Axis II disorder (and neither criteria set for BPD) was assessed at baseline using a semistructured interview of demonstrated reliability. Over 94% of surviving patients were reinterviewed about their psychosocial functioning blind to all previously collected information at three distinct follow-up waves: 2-, 4-, and 6-year follow-up. The psychosocial functioning of borderline patients improved substantially over time, with the percentage meeting criteria for good overall psychosocial functioning increasing from 26% at baseline to 56% during the third wave of follow-up. Despite this improvement, borderline patients functioned significantly more poorly than Axis II comparison subjects, particularly in the area of vocational achievement. However, a more detailed examination revealed that borderline patients who had experienced a symptomatic remission during the course of the study functioned significantly better both socially and vocationally than never-remitted borderline patients. More specifically, they were significantly more likely to have a good relationship with a spouse/partner and at least one parent, good work/school performance, a sustained work/school history, a GAF score of 61 or higher (43% vs. 0% 6 years after their index admission), and to have good overall psychosocial functioning (66% vs. 27% at 6 year follow-up). Taken together, the results of this study suggest that psychosocial improvement is both common among borderline patients and strongly related to their symptomatic status.

The McLean Study of Adult Development (MSAD): overview and implications of the first six years of prospective follow-up.

The McLean Study of Adult Development (MSAD) began 12 years ago. It is the first NIMH-funded prospective study of the course and outcome of borderline personality disorder (BPD). After careful analysis of the first six years of follow-up, 5 main findings concerning the symptomatic and psychosocial course of BPD have emerged from this study. The first finding is that remissions are far more common than previously recognized (about 74%). The second is that these remissions are quite stable and thus, recurrences are quite rare (about 6%). The third finding is that completed suicides are far more rare than anticipated (about 4% vs. 10%). The fourth finding is that a "complex" model of borderline psychopathology best describes BPD. In this model, some symptoms resolve relatively quickly, are the best markers for the disorder, and are often the immediate reason for needing costly forms of treatment, such as psychiatric hospitalizations. We termed these symptoms (e.g., self-mutilation, help-seeking suicide threats or attempts) acute symptoms. Other symptoms resolve more slowly, are not specific to BPD, and are closely associated with ongoing psychosocial impairment. We termed such symptoms (e.g., chronic feelings of intense anger, profound abandonment concerns) temperamental symptoms. Fifth, it was also found that borderline patients were improving psychosocially over time, particularly remitted borderline patients; psychosocial functioning of remitted patients continued to improve as time progressed, suggesting that they were somewhat belatedly achieving the milestones of young adulthood and not simply returning to a prodromal level of functioning. Taken together, these results suggest that the prognosis for BPD is better than previously recognized.

Axis I comorbidity in patients with borderline personality disorder: 6-year follow-up and prediction of time to remission.

OBJECTIVE: The purpose of this study was to assess the prevalence of axis I disorders among patients with borderline personality disorder over 6 years of prospective follow-up. METHOD: A semistructured interview of demonstrated reliability was used to assess presence or absence of comorbid axis I disorders in 290 patients who met Revised Diagnostic Interview for Borderlines criteria and DSM-III-R criteria for borderline personality disorder and 72 patients who did not meet these criteria but did meet DSM-III-R criteria for another axis II disorder. Over 94% of surviving patients were reinterviewed about their axis I disorders at 2-year, 4-year, and 6-year follow-up periods. RESULTS: Although the patients with borderline personality disorder experienced declining rates of many axis I disorders over time, the rates of these disorders remained high, particularly the rates of mood and anxiety disorders. Patients whose borderline personality disorder remitted over time experienced substantial decline in all comorbid disorders assessed, but those whose borderline personality disorder did not remit over time reported stable rates of comorbid disorders. When the absence of comorbid axis I disorders was used to predict time to remission, the absence of substance use disorders was a far stronger predictor of remission from borderline personality disorder than was the absence of posttraumatic stress disorder, mood disorders, other anxiety disorders, or eating disorders, respectively. CONCLUSIONS: The results of this study suggest that axis I disorders are less common over time in patients with initially severe borderline personality disorder, particularly for patients whose borderline personality disorder remits over time. The findings also suggest that substance use disorders are most closely associated with the failure to achieve remission from borderline personality disorder.

Mental health service utilization by borderline personality disorder patients and Axis II comparison subjects followed prospectively for 6 years.

OBJECTIVE: The purpose of this study was to describe the psychiatric treatment received by a well-defined sample of patients with borderline personality disorder and Axis II comparison subjects over 6 years of prospective follow-up. METHOD: 362 inpatients were interviewed about their treatment histories during their index admission (1992-1995). 290 patients met both Revised Diagnostic Interview for Borderlines and DSM-III-R criteria for borderline personality disorder and 72 met DSM-III-R criteria for at least 1 nonborderline Axis II disorder (and neither criteria set for borderline personality disorder). Over 94% of surviving patients were re-interviewed about their psychiatric treatment histories 2, 4, and 6 years later. RESULTS: Only 33% of borderline patients were hospitalized during the final 2 years of the 6-year follow-up, a substantial decline from the 79% who had prior hospitalizations at baseline. Much the same pattern emerged for day and/or residential treatment (from 55% to 22%). In contrast, about three quarters of borderline patients were still in psychotherapy and taking psychotropic medications after 6 years of follow-up. Additionally, over 70% of borderline patients participating in these outpatient modalities did so for at least 75% of each follow-up period. While rates of intensive psychotherapy declined significantly over time (from 36% to 16%), rates of intensive polypharmacy remained relatively stable over time, with about 40% of borderline patients taking 3 or more concurrent standing medications during each follow-up period, about 20% taking 4 or more, and about 10% taking 5 or more. CONCLUSIONS: The results of this study suggest that the majority of borderline patients continue to use outpatient treatment in a sustained manner through 6 years of follow-up, but only a declining minority use more restrictive and costly forms of treatment.

The longitudinal course of borderline psychopathology: 6-year prospective follow-up of the phenomenology of borderline personality disorder.

OBJECTIVE: The syndromal and subsyndromal phenomenology of borderline personality disorder was tracked over 6 years of prospective follow-up. METHOD: The psychopathology of 362 inpatients with personality disorders was assessed with the Revised Diagnostic Interview for Borderlines (DIB-R) and borderline personality disorder module of the Revised Diagnostic Interview for DSM-III-R Personality Disorders. Of these patients, 290 met DIB-R and DSM-III-R criteria for borderline personality disorder and 72 met DSM-III-R criteria for other axis II disorders (and neither criteria set for borderline personality disorder). Most of the borderline patients received multiple treatments before the index admission and during the study. Over 94% of the total surviving subjects were reassessed at 2, 4, and 6 years by interviewers blind to previously collected information. RESULTS: Of the subjects with borderline personality disorder, 34.5% met the criteria for remission at 2 years, 49.4% at 4 years, 68.6% at 6 years, and 73.5% over the entire follow-up. Only 5.9% of those with remissions experienced recurrences. None of the comparison subjects with other axis II disorders developed borderline personality disorder during follow-up. The patients with borderline personality disorder had declining rates of 24 symptom patterns but remained symptomatically distinct from the comparison subjects. Impulsive symptoms resolved the most quickly, affective symptoms were the most chronic, and cognitive and interpersonal symptoms were intermediate. CONCLUSIONS: These results suggest that symptomatic improvement is both common and stable, even among the most disturbed borderline patients, and that the symptomatic prognosis for most, but not all, severely ill borderline patients is better than previously recognized.

Suggested guidelines for e-mail communication in psychiatric practice.

BACKGROUND: Physicians and patients are increasingly communicating with one another by e-mail concerning administrative issues, medications, and other aspects of care. The objective of this article is to review existing guidelines for general physicians communicating with patients by e-mail as the basis for developing more specific guidelines for psychiatric practice. METHOD: We review e-mail guidelines previously developed by the American Medical Informatics Association, subsequently promulgated by the American Medical Association, and consider each suggestion for clinical and administrative practice from the perspective of psychiatric practice. Case vignettes illustrate several of these issues. RESULTS: We suggest expansion and/or modification of existing guidelines to address more directly issues of specific concern in psychiatric practice. CONCLUSION: Existing general guidelines concerning the use of e-mail in medical practice are useful starting points for psychiatric practice. Psychiatrists must pay particular attention to issues of confidentiality, communicative tone, and professional boundaries. With cautious application, e-mail may provide a useful tool for enhancing communication and treatment options for psychiatrists and their patients.
